Compact Floribunda Rose plant named ‘Poulpal019’

ABSTRACT

A new garden rose plant of the floribunda class which has abundant, pink flowers and attractive foliage. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

SUMMARY OF THE INVENTION

Botanical classification: Rosa hybrid.

Variety denomination: ‘Paulpal019’.

The present invention constitutes a new and distinct variety of gardenrose plant that originated from a controlled crossing between the femaleseed parent ‘Poulmanti’, described and illustrated in U.S. Plant Pat.No. 11,540 issued Oct. 3, 2000, and the male pollen parent, an unnamedseedling from the same inventor.

The two parents were crossed during the summer of 1997, and theresulting seeds were planted in a controlled environment in Fredensborg,Denmark. The new variety is named ‘Poulpal019’.

The new variety may be distinguished from its female seed parent,‘Poulmanti’ by the following combination of characteristics:

-   -   1. While the seed parent ‘Poulmanti’ has petal count of 40 to        50, ‘Poulpal019’ has 55 to 60 petals.    -   2. The upper surface of the outer flower petals on ‘Poulmanti’        are Red Group 55B-55C. ‘Poulpal019’ is White Group 155B with a        faint overlay of Red-Purple Group 62D.

The new variety may be distinguished from its male pollen parent by thefollowing combination of characteristics:

-   -   1. The pollen parent has a red flower color, while flowers of        ‘Poulpal019’ are medium pink.    -   2. The pollen parent has a flower diameter of 40 mm. Flowers of        ‘Poulpal019’ are 60 to 65 mm.

The objective of the hybridization of this rose variety was to create anew and distinct variety for garden use with unique qualities, such as:

-   -   1. Uniform and abundant pink flowers;    -   2. Vigorous, but compact growth;    -   3. Disease resistance;    -   4. Large flower size;    -   5. Dark glossy foliage.

This combination of qualities is not present in previously availablecommercial cultivars of this type, known to the inventors, anddistinguish ‘Poulpal019’ from all other varieties of which we are aware.

As part of the rose development program, Mogens N. Olesen germinated theseeds from the aforementioned hybridization during winter of 1997 andconducted evaluations on the resulting seedlings in a controlledenvironment in Fredensborg, Denmark.

‘Poulpal019’ was selected in the spring of 1998 by the inventor as asingle plant from the progeny of the aforementioned hybridization.

Asexual reproduction of ‘Poulpal019’ by traditional budding and rootedcuttings was first done by Mogens N. Olesen in the nursery inFredensborg, Denmark in July 1998. This initial and other subsequentasexual propagations conducted in controlled environments havedemonstrated that the characteristics of ‘Poulpal019’ are true to typeand are tranmitted from one generation to the next.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘Poulpal019’, as observed in itsgrowth in a field nursery in Jackson County, Oreg. Observed plants are 3years of age, and were grown on Rosa multiflora understock. Colorreferences are made using The Royal Horticultural Society (London,England) Colour Chart, 1995, except where common terms of color areused.

For a comparison, several physical characteristics of the rose variety‘Poulac007’, a rose variety from the same inventors described andillustrated in U.S. Plant Pat. No. 15,794, are compared to ‘Poulpal019’in Chart 1.
